CK, do not take your H's spew personally. It really has nothing to do with you. Distance yourself from him. Do what you can to have no contact with him unless absolutely necessary. This is for you. The less you listen to his garbage the easier on you it becomes. Take this time to work on yourself and become the best you you can be.
Yes, they do pull away from everyone. They are running trying to escape their pain. They figure a new life with new people will 'fix' them. All it is is a band-aid. This stage is called Replay and they will remain in it until they stop running and examine themselves inside and start to resolve the issues that have been pushed way down. An ow if there is one will show up in this stage.
Please take care CK and know that you are not alone. We're all here to help each other through a sitch that none of us asked for. Patience is the key to this whole thing. It is not a short or easy roller coaster ride.
